Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically a fire safety door. Background Technology

[0002] With increasing public awareness of safety and stricter national requirements for fire safety, fire safety doors are being used more and more widely in homes and commercial establishments. As a crucial measure for fire-resistant partitioning in buildings, the application and demand for fire doors are continuously growing.

[0003] In existing technologies, fire safety door sealing strips are generally installed on the edge of the door. As the sealing strips age and are continuously squeezed, the sealing effect of the safety door body becomes poor. Furthermore, there is no buffer zone between the safety door body and the door frame in existing technologies. When an explosion occurs inside the building, the shock wave generated by the explosion can easily directly damage the safety door body.

[0004] For example, the fire safety door device disclosed in Chinese Patent Publication No. CN206397366U includes a safety door device body, a safety door made of copper-aluminum alloy material installed on the side of the safety door device body, and a safety door frame made of hard, heat-resistant and waterproof material installed on the side of the safety door, so that when the safety door and the safety door frame are closed together, the fire safety door device can be sufficiently robust.

[0005] However, in that application, the safety door and the safety door frame are relatively fixed when connected. In the event of an explosion, the safety door body and its connection points are prone to rigid fracture, causing irreparable damage. Therefore, this application provides a fire safety door that solves the problems of poor sealing performance and rigid damage easily caused by impact in the prior art. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a fire safety door.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a fire safety door, including two safety door bodies that open in opposite directions, including a mounting frame and two safety door bodies that open in opposite directions, a mounting groove is opened on one side of the mounting frame, a vertical mounting bracket is set inside the mounting groove, the safety door body is rotatably connected to the mounting bracket, and a reinforcing bolt is detachably connected between the two safety door bodies;

[0008] A sealing plate is provided on one side of the safety door body, and a pressing plate is provided on the other safety door body opposite it. The pressing plate is used to press the sealing plate to seal the connection between the two safety door bodies.

[0009] As an optimization, the width of the mounting groove gradually decreases from top to bottom, the mounting bracket can rotate toward the mounting groove, the lower end of the mounting bracket is rotatably connected to the bottom of the mounting groove, and a reinforcing spring is connected between the upper end of the mounting bracket and the upper part of the mounting groove.

[0010] The bottom of the mounting frame is provided with a pre-embedded reinforcing bolt, which is located inside the concrete.

[0011] As an optimization, the sealing sheet is set to fit the height direction of the safety door body, and a plurality of telescopic rods are provided on one side of the safety door body, with the clamping sheet connected to the extended end of the telescopic rods;

[0012] The clamping plate has a receiving groove on the side opposite to the safety door body. When the telescopic rod extends, the clamping plate moves to the outside of the sealing plate, the sealing plate extends into the receiving groove, and the sealing plate fits against the side of the safety door body.

[0013] As an optimization, connecting seats are provided on both sides of the safety door body, and the reinforcing bolt is installed through the connecting seats of the two safety door bodies.

[0014] As an optimization, the sealing plates of the two safety door bodies are arranged in a centrally symmetrical manner.

[0015] The fire safety door proposed in this solution has the following advantages:

[0016] The mounting frame of this application is provided with a mounting groove, which allows the safety door body to swing along the depth direction of the mounting groove when it is impacted, thereby preventing the rigid structure of the safety door body from breaking when it is subjected to a large impact, ensuring the efficient use of the safety door body, and improving the service life and protective effect of the safety door body.

[0017] Sealing plates are installed on both sides of the safety door body. The sealing plates are pressed and fixed by clamping plates to ensure the sealing effect of the safety door body. Attached Figure Description

[0024] like Figures 1-5 As shown, a fire safety door includes two opposing safety door bodies 1, including a mounting frame 2 and two opposing safety door bodies 1. A mounting groove 3 is opened on one side of the mounting frame 2, and a vertical mounting bracket 4 is arranged inside the mounting groove 3. The safety door body 1 is rotatably connected to the mounting bracket 4, and a reinforcing bolt 5 is detachably connected between the two safety door bodies 1.

[0025] A sealing plate 6 is provided on one side of the safety door body 1, and a pressing plate 7 is provided on the other safety door body 1 opposite to it. The pressing plate 7 is used to press the sealing plate 6 to seal the connection between the two safety door bodies 1.

[0026] The front and back of the safety door body 1 are evenly provided with sealing plates 6, clamping plates 7, and reinforcing bolts 5. A sealing strip is also provided on the outer periphery of the safety door body 1.

[0027] like Figure 1 and Figure 3 As shown, the width of the mounting groove 3 gradually decreases from top to bottom, the mounting bracket 4 can rotate toward the mounting groove 3, the lower end of the mounting bracket 4 is rotatably connected to the bottom of the mounting groove 3, and a reinforcing spring 8 is connected between the upper end of the mounting bracket 4 and the upper part of the mounting groove 3.

[0028] The bottom of the mounting bracket 4 is provided with a pre-embedded reinforcing bolt 11, which is located inside the concrete.

[0029] The bottom or top of the safety door is connected to the building wall by a pre-embedded reinforcing bolt 11. When the pre-embedded reinforcing bolt 11 is located at the top, the width of the mounting groove 3 should gradually increase from top to bottom, and the corresponding reinforcing spring 8 should be set at the lower end of the mounting groove 3.

[0030] like Figure 1 As shown, the sealing sheet 6 is arranged to fit the height direction of the safety door body 1, and a plurality of telescopic rods 10 are provided on one side of the safety door body 1. The pressing sheet 7 is connected to the extended end of the telescopic rod 10.

[0031] The clamping plate 7 has a receiving groove on the side opposite to the safety door body 1. When the telescopic rod 10 extends, the clamping plate 7 moves to the outside of the sealing plate 6, and the sealing plate 6 extends into the receiving groove. At the same time, the sealing plate 6 fits against the side of the safety door body 1.

[0032] The telescopic pole 10 may be an electric telescopic pole 10. Correspondingly, this application should also include a power supply and a controller for maintaining the use of the electric telescopic pole 10.

[0033] The sealing sheet 6 is fitted to the safety door body 1, and the pressing sheet 7 tends to press towards the safety door body 1. By pressing the end of the sealing sheet 6 with the pressing sheet 7, the sealing sheet 6 is brought into close contact with the safety door body 1.

[0034] Both sides of the safety door body 1 are provided with connecting seats 9, and the reinforcing bolt 5 is provided through the connecting seats 9 of the two safety door bodies 1.

[0035] The sealing plates 6 of the two safety door bodies 1 are arranged in a centrally symmetrical manner.

[0036] In actual use, the safety door body 1 is rotatably connected to the mounting frame 4, and when the safety door body 1 is closed, it is sealed to the mounting frame 4 and the building wall.

[0037] When the two safety door bodies 1 are closed relative to each other, the two safety door bodies 1 are connected by the reinforcing bolt 5;

[0038] The telescopic rod 10 extends and presses the sealing plate 6 through the clamping plate 7, so that the sealing plate 6 fits and seals against the safety door body 1;

[0039] When the safety door body 1 is subjected to a strong and excessive impact, the pre-embedded reinforcing bolt 11 breaks first. Subsequently, the safety door body 1 and the mounting bracket 4 tilt towards the mounting groove 3. The reinforcing spring 8 cushions the safety door body 1, so that the safety door body 1 can be buffered when it is impacted, and the shock wave can prevent damage to the safety door body 1. After the shock wave recedes, the safety door body 1 can be reset under the action of the reinforcing spring 8, and still maintain its sealing and fireproof function.
